And for those who have the Synaptics touchpad, I've found a way to make
the touchpad almost work. You can apply the following patch which will
make kernel use hid-rmi handle the device without blacklisting hid-
mulitouch,

One left issue is the single clicking is not sensitive enough. I need to
let my finger linger on the touchpad for a while (like 0.5s). I'll send
the patches upstream after fixing this issue.

Bug description:
Hello
The MSFT touchpad of this Lenovo Legion-5 15ARH05 laptop is not reacting at
all (pointer and click never move when touchpad is touched). This has been
reported by other users in various websites, with various linux systems
including other Ubuntu systems, but I saw no launchpad bug so I post one.
Example of websites covering the issue :
- https://askubuntu.com/questions/1253830/lenovo-legion-5-touchpad (exactly
the same laptop)
- https://www.linux.org/threads/lenovo-legion-5-touchpad.29536/ (similar
laptop)
xinput indentifies it as MSFT0001:00 04F3:3140

Thanks a lot for your time. It does not help, but I can confirm what
was reported on askubuntu by another user : the touchpad does work on
Windows.
